Humans obtain energy in a number of different ways. about half of the electrical energy in the u. s. is generated by burning coal, largely because coal is very inexpensive. but some electrical energy is generated by capturing sunlight with solar panels.

which of these is a reason why many people want to use more solar panels and less coal?

a.
coal is a renewable resource, while sunlight is a nonrenewable resource.
b.
coal is more abundant than sunlight.
c.
burning coal tends to harm the environment more than using solar panels.
d.
coal energy is cleaner than solar energy.

C. Burning coal tends to harm the environment more than using solar panels.

Explanation:

When coal is burned, it reacts with the oxygen in the air. This reaction converts the stored potential energy, which turns into thermal energy, which is released as heat. But it also produces methane and carbon dioxide which is released into the air.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
